It doesnt seem to work.. (twitter4j setRpp)

tyronwinter

Hey guys, i'm fairly new to processing

but i found this code from a guy that he made in 2011.

Putting in a hashtag and it becomes a visual.. now processing says the SetRpp function

doesnt exist..

Is it because this code is pretty old?

anyway it seems really short and efficient.

would appreciate some help!

(i have everything set up in the library twitter4j-core etc)

Thanks!

you seem to be missing imports

koogs

setRpp is in twitter4j version 2.1.0

http://twitter4j.org/oldjavadocs/2.1.0/twitter4j/Query.html

but isn't in (what i think are) the current docs

http://twitter4j.org/javadoc/twitter4j/Query.html

try setCount() instead - the descriptions are similar (rpp = results per page)

tyronwinter

Thanks so much for you reply dude! so i've changed it.. and i had been changing the setRpp but then it says: "Cannot find a class or type named "tweet"

i realized i forgot to import the files from the library aswel.. so i did that

what could it mean by tweet? i read somewhere that i had to change it to status, but that doesnt work!

koogs

QueryResult result = twitter.search(query);
ArrayList tweets = (ArrayList) result.getTweets();

this fills the list of results. maybe twitter.search() is returning different items now.

2011 is 5 years ago! a lot can change in 5 years (2 major api revisions of twitter4j for one thing)

In general, your error messages give you a line number. You need to look at the line number to see inspect the code that is wrong! Clicking on the error may take you to that line number.

For example (I don't know), if you wrote:

tweet t = mytweet;

Then you are referring to an object class "tweet" but your library doesn't define any such thing. Processing is case-sensitive -- the library (and the examples you started with) define a class "Tweet", not "tweet." So, no class or type found until you use the correct class name as defined in the library you are using:

Tweet t = mytweet;

koogs

yes, the results are now of type Status

http://twitter4j.org/javadoc/twitter4j/QueryResult.html#getTweets--

and here's the definition of Status

http://twitter4j.org/javadoc/twitter4j/Status.html

which contains text.

and getFromUser() now seems to be getUser(),which returns a User. who has a name and a screenname...

tyronwinter

Yep that's true! i changed a lot in the past time got this now.. it just says unexpected token.. am i close you think or should i just throw in the towel ;))

Status t=(Status) .get(i);
User u=(User) t.getUser();
String user=u.getName();

lines 1, 2, 3 look out of place

line 37 looks like it's missing something. ditto line 39

did you globally find / replace something you shouldn't've?
